Acknowledgements
Many people supported me in one way or another in this project, and deserve to be acknowledged. For sacrificing many weekend days so I could write, my wife Kathleen. Eric Flint, for giving me the general thought that became Grand Central Arena; my beta-reading group, especially my Loyal Lieutenant Shana; and Keith Morrison and Mary Dell, who helped bring the images in my head to life (as can be seen at www.grandcentralarena.com).
